Butt-end of an isolated baulk in the NE corner of k107. It is a natural accumulation which is located between k107 and unit J2 to the east. It results from the mis-match of the German trench in unit B6, f545, (which tried to locate the north edge if the second apron, f556) and the grid system in use during the course of this excavation.
